......Apart from the baby?!
DC1 will be a winter baby, and I had a sudden realisation that I'm not sure what you put in the carrycot part of a pram! Does it need sheets? A waterproof cover? If so, will Moses basket sheets fit? And is the mattress inside comfy and supportive enough, or is it best to buy a separate one?
And then, when baby is inside, what do you put them in? A snowsuit/pram suit thingy, or do you treat it as a little bed on wheels and do sheets/wraps and blankets? I really have no idea!
